Rotork CVA Range - CVQ Quarter-Turn Control Valve Actuator

Brand: Rotork PLC

The CVA range of linear and quarter-turn actuators provide an electrically powered process control operator suitable for most control valve types and sizes.

The CVA sets a new standard for process control and valve actuation.

The Rotork CVQ quarter-turn, electric process control actuator, offers a highly accurate and responsive method of automating control valves, without the complexity and cost of a pneumatic supply.

With an increased focus on production costs and efficiency, accurate control of product through the pipeline is paramount.

With resolution figures better than 0.1% and the ability to eliminate position overshoot, the Rotork CVQ helps to maximize product quality and plant capacity.

The CVQ delivers a range of sizes suitable for almost all quarter-turn control valve applications requiring highly accurate positioning.

It offers end users high standards in performance, build quality and overall value.
